Both winter and summer burns caused earlier appearance of flowers and pitchers of trumpet-leaf. Pitcher height was reduced during the first postfire growing season, returning to control values in the second. No change in patterns of production followed the summer burn. Soil nutrient status was not significantly altered by either burn. Tissue nutrient changes following the burns were of short duration, lasting through most of the first postwinter burn growing season and through only the end of the growing season following the summer burn. In general, summer burns appeared to be less detrimental to growth of pitcherplants in south Georgia. [From author's abstract]
